The majority of women experience vasomotor symptoms (VMS) such as hot flashes (HF) and night sweats as they transition through menopause, and a substantial minority experience considerable distress and diminished role functioning. Until recently most women found relief through hormone therapy (HT), but concern about the health risks associated with HT has left women with few effective and safe choices for relief from their symptoms other than their own coping strategies. A variety of results from both population and laboratory studies suggest that stress and HF are correlated and that HF are more severe in women with lower coping abilities, but evidence is far from conclusive. Consequently, investigators have called for trials to evaluate the effect of stress reduction interventions on HF. Mindfulness-Based Stress Reduction (MBSR) is a widely available manualized program shown to be an effective adjunctive intervention in reducing medical symptoms and psychological distress for a wide range of stress-related disorders. In a small preliminary study using MBSR we found reductions in HF severity scores and increases in menopause-related quality of life (QOL). This R21 proposal is for a pilot randomized trial of MBSR compared to a wait-list control group for 120 menopausal women experiencing seven or more HF/day of moderate to severe intensity. It aims to:
